Dogs Change Facial Expression When Humans Pay Attention
Dog faces don't just make for great internet videos—they can also teach us about the evolution of dog domestication. A new study shows that when given human attention, dogs will produce a wider range of facial expressions. Scientists gauged dog reactions while being watched by a human versus when the human had their back turned. While being watched, the dogs used a wider variety of facial movements. Dogs have lived alongside humans for 30,000 years, and may have evolved this ability to better communicate.
